Fearing retaliation, the US urged Iran to avoid escalation and attacks on US targets.
How about urging Israel to stop their genocide, ceasefire and let human aid, food trucks and all that into Gaza. How about stopping Israel from invading Rafah and murdering thousands of people again.
Trump assassinated an Iranian General and their response was more level headed than anything Israel has done since October 8th. The US is worried about the wrong country.
Since there is some opinion that this attack is only hours away, let's recap.
If the attack comes from mainland Iran, all shit is going to come loose. Look up "War of the Cities". The US most certainly will be involved. For its part, Iran seems to indicate that won't happen.
The US seems to believe that, and has moved the Eisenhower battle group closer to Yemen to knock down what they throw up.
Leaving Hezbollah and Hamas. Hezbollah has thousands of missles and Lebanon has moved their population as they can out of conflict zones. This didn't go over well with the Lebanese and there seems to be a problem within Hezbollah itself.
Hamas is pretty much combat ineffective at this point.
